I'm using JMeter for performance testing and generate an CSV file for data analysis.
How should I add JMeter Variable names to the CSV output? It seems that only pre-defined columns can be added (see screenshot).
This is my log-file:
14/03/2014,Login,OK,982
14/03/2014,Search,OK,2182
14/03/2014,Login,OK,3982
I would like to add a column with the ${username} to generate something like:
14/03/2014,Login,OK,982,user1
14/03/2014,Search,OK,2182,user7
14/03/2014,Login,OK,3982,user9
Try to pass sample_variables property, for example as command-line parameter -Jsample_variables=username,some_other_var
Also see FlexibleFileWriter plugin if you need custom formatting http://jmeter-plugins.org/wiki/FlexibleFileWriter/?utm_source=jmeter&utm_medium=helplink&utm_campaign=FlexibleFileWriter

I have multiple API request bodies and Im passing them using txt file in CSV Data Set Config. This API request bodies have certain values to parameterize. How Do I acheive this? something like paramertize inside parameterized csv file.
If your CSV file contains JMeter Functions or Variables which you want to evaluate in the runtime you need to wrap the variable(s) defined in the CSV Data Set Config into __eval() function
For example if you have:
test.csv file with the single line containing ${foo} and CSV Data Set Config reading this file into some-variable
User Defined Variables which assigns the variable foo the value of bar
And a couple of Debug Samplers for visualization
You will see that:
${some-variable} will return ${foo}, basically the line from the CSV file
${__eval(${some-variable})} will return bar because the variable will be evaluated and its respective value will be resolved.
Can we use csv file to get data in cucumber?
By using
#RunWith(SerenityParameterizedRunner.class)
#UseTestDataFrom(value="testdata/status-levels.csv")
It is asking for #Test
as we should not use test in cucumber.
Can any one tell me how to read a file from csv file in cucumber?
You can use Transformer class. You need to customize your transformer and then use it in your stepdefinition.
I am trying to understand if it's possible to change the model output format to .csv instead of the default .mat file when simulating a model using dymosim.exe.
I can do this in dymola itself by using the function "convertMATtoCSV" in the base Data files library. Something like below,
DataFiles.convertMATtoCSV("output.mat", {"t"}, "output.csv");
Is there a way to do this conversion using dymosim.exe?
Kindly advise.
Thanks.
Note: cmd "dymosim.exe -h" has some options for .csv but I am not sure how to use this.
No, it is currently not possible to have dymosim.exe generated by Dymola write the result as csv-file. The CSV-options used by dymosim.exe are only for running multiple simulations.
You can:
Generate a txt result instead, if that is easier to handle for you. (By setting Simulation Setup>Output>Textual data format, this is stored as last element of settings in dsin.txt).
Perform the conversion using dymola\bin\alist.exe
Have the model write a cvs-file as well
Set up to perform this as a post-processing command in Dymola 2017 FD01.
New to PDI here. Need to output data from a view in a postgresql database to a file daily. The output file will be like xxxx_20160427.txt, so need to append the dynamic date in the file name. How to do it?
EDIT-----------------
I was not clear here by asking how to add dynamic date, I was trying to add not just date but optional other parts to the file name. E.g adding a serial no (01) at the end: xxxx_2016042701.txt etc. So my real question is how to make a dynamic file name? In other ETL tool e.g. SSIS it will be a simple expression. Not sure how it is done in PDI?
In your Text file output step, simply check "Include date in filename?" under the files tab.
You can create a dynamic filename variable with a Modified Java Script value STEP.
and then in the Text File Output STEP click on "Accept file name from field", and select your variable declared from previous step (filename_var on this example).
I have a CSV input file with commas. I need to change the delimiter to pipe. Which step should I use in Pentaho kettle? Please do suggest.
Thanks!
Do not use big gun when you try to shoot small target. Can use sed or awk. Or when you want to integrate with kettle, can use step to run shell script and within script use sed for example.
If your goal is to output a pipe separated CSV file from data within a transform and you're already running Kettle, just use a Text File output step.
If the goal is to do something unusual with CSV data within the transform itself, you might look into the Concat Fields step.
If the goal is simply to take a CSV file and write out another CSV with different separators, use the solution #martinnovoty suggests.
You can achieve this easy:
Add a javascript step after the load your csv step into a variable "foo" and add this code onto the js step:
var newFoo = replace(foo,",", "|");
now your cvs file is loaded in newFoo var with pipes.
